Examples

Example #1 gmp_intval example

<?php
// displays correct result
echo gmp_intval("2147483647") . "\n";

// displays wrong result, above PHP integer limit
echo gmp_intval("2147483648") . "\n";

// displays correct result
echo gmp_strval("2147483648") . "\n";
?>

The above example will output:

This function returns a useful result only if the number actually fits the PHP integer (i.e., signed long type). To simply print the GMP number, use gmp_strval.
